While its properties are not the same, tea tree oil serves as a good substitute for Epsom salt in the bath. The herbal therapy strengthens the body's immune system and can even be used as a mouth wash. Adding the oil to warm water can improve respiratory function.
Epsom salt itself is not actually a salt, it's a naturally occurring mineral compound that is made up of sulfate and magnesium. Its name is derived from a saline spring located at Epsom in Surrey, England. The "salt" is readily absorbed through the pores of the skin, which in turn provides a variety of health benefits.
The soak has been confirmed to reduce inflammation, improve nerve function and help people who are suffering from hardening arteries. The sulfates in Epsom salt contribute to flushing out toxins in the body and easing migraine headache pain.
